Table II. LA results by size of liver metastases.
Figure 1. (a) Recurrent colorectal metastasis of the liver in a patient who had already undegone a partial resection of the right lobe. A helical CT scan shows a hypoattenuating lesion 2.7 cm in diameter in segment 3 of the left lobe.

Figure 2. (b) 24 hours after percutaneous laser ablation a contrast-enhanced CT scan shows complete ablation of the lesion. The necrotic area appears as a hypoattenuating area 4.5 cm in diameter. During follow-up (40 months) new lesions appeared in segment 2, which were successfully treated with percutaneous laser ablation.
